You should very lightly tighten the containment straps at first so that you can look around the guitar and make sure that the straps are properly positioned. The cross shaped management straps which are located at the sides of the guitar are adjustable. They should be adjusted to sit in the middle of the valley at the sides of the guitar(shown in picture).

The containment straps should sit flat against the surfaces of the guitar. If they are not sitting flat. Flip them over till they do sit flat.

I have taken a picture to show you how I position the containment straps at the heel of my guitar. This should help give you a good idea on how I personally like to have a Setti Guitar Harness Strap positioned. As you can see from the photo, the containment straps are positioned more towards the lower part of the heel of the guitar. And the center of the heel of the guitar is positioned between the two loops of the Setti Guitar Harness Strap. The Setti Guitar Harness Strap is very adjustable and how you position your own is just a matter of personal preference.

When everything is positioned properly go ahead and lightly tighten the containment straps even further. One at a time.
